Dr. Irina Bräutigam (Universität Archangelsk): "Infinite Jacobi Matrices"

Nov 03, 2016 from 02:00 PM to 03:30 PM

Abstract:

The classical three-diagonal and block infinite Jacobi matrices are discussed.  Some conditions for minimality, maximality, and nonmaximality of deficiency numbers of the minimal operator generated by the above Jacobi matrices are presented. The obtained results are applied to one-dimensional Schrödinger operator with point interactions.
